I’ll put it at a 2. The only way that I have seen AI go beyond a 1 has been when used by people without a talent in art use AI art as a way to assist in visually telling their story, like using it to help their D&D campaign or to provide the visuals for a comic book.

There is still a creative vision using AI. It just happens to be by someone without an artistic talent.

This is actually a pretty good use case: one off, inconsequential, wouldn’t exist outside the scenario (or would even be considered to ask an artist), and adds a massive amount to a small party.
